6 Claims.

The object of the invention is tov provide a frame for use in connectionwith dyeing machines employed for dyeing yarn in the skein, so that theskeins may be readily lowered in the dyeing vat and removed therefromwithout the necessity for the operator or other workmen having to enterthe vat with the hazards, such as the possibility of an overhangingweight falling, which attend such action; to provide a frame for skeindyeing apparatus which will maintain positively a definite spacedrelation of the skein hangers during the dyeing operation, so that whenthe skeins are removed, they may be placed on a truck adapted to receivethe skein hangers and maintain the relation which they have when mountedin the frame; and generally to provide a device of the kind indicatedwhich is of comparatively simple form and susceptible of cheapmanufacture.

With this object in view, the invention consists in a construction andcombination of parts of which a preferred embodiment is illustrated inthe accompanying drawings but to which embodiment the invention is notto be restricted. Continued use in practice may dictate certain changesor alterations and the right is claimedI to make any which fall withinthe scope of the annexed claims. Y

In the drawings:

Figure 1 is a side elevational view of a frame constructed in accordancewith the invention and the trucks in connection with which the frame isused.

Figure 2 is an end elevational View of the same.

Figure 3 is a top plan View.

Figure 4 is a view similar to Figure 2 but showing the arrangement afterskein hangers have been delivered to the trucks.

Figure 5 is a sectional view on the plane indicated by the line 5 5 ofFigure 1.

Figure 6 is a detail elevational view, partly in section, of the truckcarried skein hanger support.

Figure 7 is a perspective view of one of the skein hangers employed.

The invention comprises a frame 10 made preferably of timbers andincorporating a vat cover 11 formed of boards spanning the frame andarranged in edge-abutting relation, so that when the frame is loweredinto the vat, the boards may constitute a cover for the latter. All ofthe boards are laid directly on the frame and secured thereto with theexception of the terminal boards A 12 which have hinged connections 14with the 1933, Serial No. 687,213 (Cl. 8-19) next adjacent boards. Whenthe frame is in po-` sition in the dyeing vat, therefore, the terminalboards or leaves 12 lie at opposite ends of the vat and may be elevatedto permit observation of the interior.

The frame is lowered into and raised from the vat mechanically by anyacceptable means and to permit its being lhandled -it is provided, abovethe top or cover 10, with the crossbars 15, these being preferablymetallic channel members' through the flanges of which extend the eyebolts 16 disposed near the extremities of the bars and having their eyesengaged with the hook b'olts 17 carried bythe frame. The bars 15 aredisposed at intermediate points in the length of the frame and at theirlongitudinal centers carry the plates 18 which project enough above theupper edges of the bars to provide ears with which the chains 19 areconnected, the chains being united by means of a common link 20 withwhich the hoistr ing and lo-wering apparatus may be connected.

The frame, on the under side, is provided with the longitudinal rails21, in the under edges of which are formed notches to serve as seats forthe skein hanger .bars 22 which are of cross-sectionally oval form asshown in Figure 7 but which on one longitudinal edge and at the ends arecut away to leave 'at faces to serve as seats for the grouping bars2`3.The grouping bars 23 are seated in the hooks of J-bolts 24 which areslidably mounted in the openings formed in the frame` 10 and which havetheir shanks threaded at the ends remote from thevhooks to threadinglyengage the eyes of hand wheels 25, the hand wheels being laterallyseated onthe upper ends of guide sleeves 26, flanged, as at 27, with theflanges drilled to receive lag screws 28 by which the guide sleeves aresecured to the frame l0. The shanks of the J-bolts at their upperextremities are provided with the handles 29 by means of which theshanks are prevented from turning, when the hand wheels 25 are rotated.The handles and the hand wheels thus serve as means for imparting axialmovement to the J-bolts while precluding angular or turning movement ofthe same in the openings in the frame through which they pass. With theskeins of yarn looped over the skein hangers, the latter are seated inthe recesses or notches in the rails 21 with the at faces at the endsdisposed downwardly, the grouping bars being carried in the hooks of theJ-bolts 24 and the skein hangers having their flat faces at the oppositeends resting on these grouping bars. After all the skein hangers areinserted in their particular seats, the J-bolts are tightened by rorootating the hand wheels 25, this tending to move the grouping bars in thedirection of the side rails 21 and effect a gripping action on the skeinhangers in their seats. The whole frame may then be lowered into thedyeing vat, when the skein becomes immersed in the dye. After immersionfor the desired length of time, the frame is elevated out o the vat andtransported in the customary manner to deposit the skein hangers andtheir contents in trucks to be transported to appropriate places fordrying. The trucks employed to receive the skein hangers are of openframe construction, being constructed preferably of pipe sections toprovide an open frame 30, the upper side rails of which are providedwith laterally extending hooks 3l constituting supports for the groupingbars. The side rails of the truck frame have secured thereto the plates32 which are notched in the upper edges as indicated at 33 to provideskein hanger seats which are spaced in accordance with the spacing ofthe seats in the frame rails 21. The plates 32 are secured to the upperside rails of the frame 30 by the Shanks of the hooks 3l which arethreaded, as indicated at 34, and which extend transversely through thetruck frame rails and through the plates, nuts 35 being threaded on theShanks of the hooks to abut the truck frame rails on one side and nuts36 being attached tothe extremities of the hook shanks, to bear againstthe plates 32 and hold them in lateral Contact with the truck framerails.

In moving the frame l0 from the dyeing vat, it is disposed over thetrucks and lowered until the grouping rails seat in the hooks 3l, whenthe skein hangers will enter the notches 33. The grouping rails andskein hangers are then released from the frame l0 by rotating the handwheels 25 in a direction to effect lowering of the hooks or longitudinalmovement in the direction opposite from the former direction ofmovement. After having been lowered sufliciently, they may be turnedangularly to free them from the grouping rails, when the frame l0 may beelevated for the reception of other grouping rails and skein hangerswith their contents.

The invention having been described, what is claimed as new and usefulis:

1. Dyeing apparatus comprising a frame, J- bolts extending downwardlythrough the frame, grouping bars seated in the hooks of the J-bolts, andskein hangers resting on the grouping bars and arranged in spacedrelation along the latter.

2. Dyeing apparatus comprising a frame, J- bolts extending downwardlythrough the frame,

grouping bars seated in the hooks ofthe J-bolts, and skein hangersresting on the grouping bars and arranged in spaced relation along thelatter, the frame being formed on the under side with spaced seats forthe skein hangers.

4. Dyeing apparatus comprising a frame, J- bolts extending downwardlythrough the frame, grouping bars seated in the hooks or" the J -bolts,and skein hangers resting on the grouping bars and arranged in spacedrelation along the latter, the J-bolts being provided with means foreiecting axial adjustment of the same to impose gripping action on theskein hangers jointly by grouping bars and frame, the frame on the underside being formed with spaced seats for the reception of the skeinhangers.
